5. The role of Robert Kennedy
Another journalist, Anthonny Summers in his book, “Goddess: The Secret Lives of Marilyn Monroe” wrote that Monroe had threatened Robert Kennedy that she would go public about their affair after he broke up ties with her. Robert Kennedy and his brother-in-law tried to prevent Monroe from doing so by fueling her growing addiction to drugs and alcohol. It is thought that Marilyn Monroe took her last breath becoming an drug addict in the ambulance and her death was later staged as a suicide.
